I'm relatively new to hibernate and its tools. I'm trying to use an xml element to move components
into a file that can be shared by a number of different mapping files

I've included below a mapping file and a component file. When I use this setup with the hbm2java tool, it correctly pulls in the relative component file. However when I try to do a hbm2ddl I get an error saying that it doesn't know how to find the relative uri because there is no base uri defined. I was hoping that I could find everything relative to the base mapping file that is being processed. Please let me know if I should be looking relative to a different directory and if so is there some way to make the hbm2java and the hbm2ddl work off of the same mapping files.

here's the ant definition of my hbm2ddl:
<taskdef name="schemaexport" classname="net.sf.hibernate.tool.hbm2ddl.SchemaExportTask" classpathref="project.class.path" />
<schemaexport properties="${commonHS}/resources/hibernate.properties" config="${commonHS}/resources/hibernate.cfg.xml" quiet="no" text="no" drop="no" delimiter=";" output="${commonHS}/schema-export.sql">

</schemaexport>


I'm using hibernate-tools-2.1.2.jar

Hibernate version:2.1.6
